Application filed July 13, 1904. Serial No. 216,403.

To all whom, it inn/y concern:

Be it known that I, WINFIELD B. PHILLIPS, a citizen of the UnitedStates, residing at Fenton, county of Genesee, State of Michigan, haveinvented a certain new and useful Improvement in AdjustableVVindow-Screens, of which the following is a specification, referencebeing bad to the accompanying drawings, which form a part of thisspecification.

My invention has for its object to provide certain new and usefulimprovements in adjustable window-screens; and it consists of theconstruction, combination, and arrangement of devices hereinafterdescribed and claimed, and illustrated in the accompanying drawings, inWhich- Figure 1 is a view in perspective, illustrating my invention.Fig. 2 is a plan view. Fig. 3 is a view in section on the line 3 8, Fig.2. Fig. 4 is a partial enlarged sectional view on the same line. Fig. 5is a view similar to Fig. 4 and showing a modification of my invention.Fig. 6 is also a view similar to Fig. 4 and showing still anothermodification of my invention.

Among the objects of my invention are to do away with the employment ofmetal clips in the construction of adjustable windowsereens; to employonly wood in the construction and adjustment of the frames; to engagethe wire netting in suitable kerfs in the frames; to constructwindow-screen frames with thefewest possible number of pieces and of theutmost symmetry and beauty attainable in adjustable screens; to providead justable window-screens with plain or ornamented front surfaces.

My invention also contemplates the general construction herein shown anddescribed.

As illustrated in the accompanying drawings, I carry out my invention asfollows: The window-screen frame as a whole is composed of two U-shapedframes, (indicated by the letters a and 6,) each composed of upper andlower bars 1 2 and an end connecting-bar 3. The upper and lower bars 1 l2 2 are each provided with a wooden cap or slide (indi cated at 0) atthe extremities of the corresponding bars, said caps or slides eachrunning in grooves on the top and bottom of the two auxiliary frames,(said grooves indicated at (L) each of the upper bars 1 1 and each ofthe lower bars 2 2 being suitably recessed to form acomplete groove (Z,or, in other words, the groove extends over both the adjacent bars atthe top and bottom of the auxiliary frames. I prefer that the grooves (1should each be convexed at the base thereof, as indicated moreparticularly in Figs. 3 and 4, although I do not limit myself thereto.The caps o are each constructed on their inner surfaces to correspondwith the shape of the base of the groove. Thus in Figs. 3 and 4 the capsare shown concaved on their inner surfaces, the said caps beingareshaped on their inner surface in cross-section, the extremities ofthe are or the lateral edges of the cap extending into the correspondingdepressions at the lateral edges of the corresponding grooves, so as tohold the two auxiliary frames in juxtaposition one with the other. InFig. 5 the cap is shown essentially U-shaped in cross-section, thegroove in the auxiliary frame being of corresponding form. In Fig. 6 thecap is shown with a V-shaped groove on its inner surface to fit into acorresponding groove in the auxiliary frame. In all of the forms ofconstruction shown it is evident that the lateral edges of the cap orslide fit into corresponding depressions in the lateral edges of thegroove to hold the frames from spreading. The wooden strips forming saidcaps are attached to the corresponding frame in any suitable manner, asby brads (indicated at 0) passed through one edge of the cap to hold thecap rigidly upon the corresponding auxiliary frame, the opposite edge ofthe cap having a sliding engagement with the adjacent auxiliary frame.

are not visible and the faces of the bars of the frame are not defacedby adjusting devices. If for ornament the faces of the frames arebeaded, the slight depressions in the upper and lower edges of the barswhich are in view when the frames are spread appear to be but acontinuation of the beads of the bar in front. The two caps arepreferably formed of suitable lengths, so as to constitute stops whenthe two auxiliary frames are pulled apart to prevent endwisc separationof said frames.

In front elevation it is obvious that the grooves and caps satisfactoryappearance.

The wire-cloth, as above observed, is prefer-. ably secured in kerfs inthe bars of the corresponding auxiliary frames (indicated atf) and maybe held in place in said kerfs in any suitable manner. The use of thesaw-kerfs to conceal the edges of the wire-cloth is made possible by theelimination of all adjusting devices from the faces of the bars. The useof tacks to fasten the wire-cloth is also done away with. \Nhere metalclamping devices are employed to hold the two frames together, the metalis more or less flexible and, moreover, unless they are very carefullymade are apt to have rough edges, preventing the running of the clampsfreely in the corresponding recesses. Moreover, the wooden slides arecheaper, while they also operate more efficiently, slide more freely,and have a more By the provision of the wooden slides the rusting ofmetal caps, clasps, or clips is also avoided. It will be seen thus thatthe upper and lower side bars of the two auxiliary frames as soconstructed are flush the one with the other at the top and that thelateral surfaces of the frames are not defaced or cut away in anymanner. The corresponding upper and lower bars of the two auxiliaryframes, in other words, are flush at the top thereof.

It will be seen that the wooden caps or slides are engaged in thecorresponding grooves intermediate the lateral surfaces of the top andbottom bars of the frames, the said bars extending up flush with the topof the said caps, and thereby concealing the caps when viewing the framein front elevation. In other words, the sliding caps are sunk flush withthe upper and lower edges of the window-screen.

What I claim as my invention is- 1. An adjustable Window-screencomprising two frames each having a top and bottom bar and connectingend bars, the top and bottom bars of each frame constructed with groovesupon their upper and lower edges respectively, and wooden caps or slidessecured to the extremities of the top and bottom bars, respectively, andhaving a sliding engagement in the corresponding groove of the oppositebar.

2. An adjustable window-screen comprising two frames, each having a topand bottom bar and connecting end bars, the top and bottom bars of eachframe constructed with grooves upon their upper and lower edgesrespectively,

- and wooden caps or slides secured to the extremities of the top andbottom bars respectively, and having a sliding engagement in thecorresponding groove of the opposite bar, the top and bottom bars ofeach of said frames being flush one with the other at the top and bottomedges of the frames.

3. An adjustable window-screen comprising two frames, each having topand bottom bars and connecting end bars, the top and bottom bars of eachframe constructed with grooves upon their upper and lower edgesrespectively, and wooden caps or slides secured to the extremities ofthe top and bottom bars respectively, and having a sliding engagement inthe corresponding groove of the opposite bar, said caps forming stops toprevent the endwise disengagement of the frames.

4. An adjustable window-screen comprising two frames, each having topand bottom bars, and connecting end bars, the top and bottom bars ofeach frame constructed with grooves upon their upper and lower edgesrespectively, and wooden caps or slides secured to the extremities ofthe top and bottom bars respectively, and having a sliding engagement inthe corresponding groove of the opposite bar,

said grooves being depressed at their outer edges below the centerthereof, and said caps being of corresponding form on their innersurfaces to hold said frames from lateral disengagement.

5. An adjustable window-screen comprising two frames each having top andbottom bars and connecting end bars, said bars kerfed on their inneredges, wire-netting drawn into said kerfs, the top and bottom bars ofsaid frames constructed with grooves on their upper and lower edgesrespectively, and wooden caps or slides secured to the extremities ofeach of the top and bottom bars respectively, and flush with the upperedges of said bars, said caps or slides having a sliding engagement inthe groove of the adjacent bar.

6. An adjustable window-screen comprising two frames each having a topand bottom bar and connecting end bars, the top and bottom barsof eachframe constructed with grooves upon their upper and lower edgesrespectively, and wooden caps or slides secured to the extremities ofthe top and bottom bars, respectively, and having a. sliding engagementin the corresponding groove of the opposite bar, the said caps or slidessecured in place intermediate the lateral surfaces of the top and bottombars of said frame.

In testimony whereof I'have signed this specification in the presence oftwo subscribing witnesses.
